ANGLE SCREW DRIVER AND ATTACHMENT.

Application filed November 20, 1925. Serial No. 70,348.

My present invention has reference to.

tools and is especially directed to a screw driver oi a small type such as is adaptable for use on radio cabinets or the like.

My primary object is theprovision ot a screw driver of this type which may be suc-' cessfully employed for driving screws in close places. r

A further object is the provision of a screw driver that includes a handle anda shank which is arranged at an angle with respect to the handle, and in which there is a universal joint connection between'the shank and handle housed in a simple but novel manner to prevent thrust between the joint elements.

A still further object is the provision of an angle screw driver of a universal joint connected type that includes a handle and a shank arranged angular-1y with respectto the handle. both handle and shank being formed from rods which have their confronting ends bent to provide interengaging eyes that are encased in a suitable housing, and wherein the knurled outer end of the handle is formed with-a rectangular socket to receive therein the rectangularend of the bit portion of a second screw driver, whereby to provide a handle GXtl1SlO11,'tl11Cl, further wherein the shank has a novel clutch means associated therewith: for holding a screw on the bit thereof or for holding a socket element on the said shank so that the device, in

addition to beingemployed as a screw driver may belikewise successfully employed for turning nuts or bolts.

To the attainment of the above broadly stated objects and others which will appear as the nature of the invention is better understood, the improvement further resides in certain novel features of con ruction. combination and operative association or arts a satisfactory embodiment of which is illustrated by the accompanying drawings.

In the drawings:

Figure 1 is a side elevation ot the improvement, partly in section.

Figure 2 is a similar view but showing one section of the housing removed and the separable screw driver or handle extension withdrawn from its socket.

Figure 3 is an edge view of the improve ment.

Figure 4: is a fragmentary enlarged elevation of the outer end of the shank, with the clamp or clutch element thereon. v

Figure '5 is a sectional view on the line of Figure l.

Figure 6 is a perspective view of the clutch element or clamp.

Figure T is a sectional view through the shank to illustrate a manner in which a socket element may be associated therewith.

Figure 8 is a fragmentary elevation of the shank with the socket member thereon.

Figure 9 is a fragmentary perspective view of the socket member and shank disassociated.

Referring now to the drawings in detail,

t-he'numeral 1 designates the handle oi": my

improvement. and 2 the shank thereof. Both the shank and handle are formed of rod members and haveth'eir confronting ends rounded upon themselves to provide in terengaging eyes 3 and l Outward ot' the eyes the members 1 and 2 are formed with rounded enlargements or bosses 5. Two of the bosses are arranged on each of the members l andj'Q, and these bosses are received in si'iitableflannular depressions (3 in sleeves 7 and S which extend angularly' from a spherical housing 9. in which the interengaging rings 3 and ti are received.

' As disclo'sed'by the drawings the housing 9 is made up of two sections 'whieh have their edges formed with ears '10, and the ears on one of the sections are designed to be bent over the confronting section. and whereby the housing may be cheaply constructed and the sections thereof readily assembled or disassociated. The bosses when seated in their bearings prevent end thrust between the inter-engaging rings 3 and e, and-by ail-arrangementas just described itwill be noted that I produce a simply constructed, cheaply manufactured angle screw driver of the universal joint type.

The outer end of the handle 1 is enlarged and knurled, as at 11, and is provided with a rectangular bore 12. The walls of this bore are designed to be contacted by a rectangular portion 13 on the bit end 14- ot' a removable screw driver 15 which affords an extension for the handle 1. Of course, the member 15 is only employed when the ham: dlel is to be extended. I

The shank 2 may be integrally formed with or have reinovably secured on its outer is formed with on outwardly extending lug 17. The shank, inward ot the lug, has er ranged thereeroimd :1 split spring sleeve l Which forms the body meniher o l u churn or chuck. From the body member there is extended outwardly directed oppositely dinposed arms .19. The ends of tharms flared out au'dly, as at 2t), and the said arms inward of the said ends are formed with lateral depressions providing outwardly bulged portions :31. *llhe uilns ii) e3" tension toward each other and are dos to grip therehetween the heed oi. the screw. which is received in the depressed portion-q of the said arms. ll hen the s rew is driven home the arms will contact with the sol-lune in which the screw h: driven, end hr Vlllltt o'l sueh content will spread away from each other. thus relens-iinn' the screw nod ermitting; the some to he driven tully home.

I have stated thut the hit to inn he remombly associated with the shrink :2; ii do sired, and in Fi ures T to h l ham- .--;l|own the shank prov led with :1 loiugiuul ml here Which extends tron the (hirer end thereof. This hollow shank, from its said outer end, is slotted longitiulineliy es Ht 2 and the terminal of the slot is aroridml with an outstnndiinr lug Ll, similar to th stop lug" above deserihed.

1n the said figures I here shown n soelte; wrench 25 associated with the shank 1?, oh thougln of course, the hit 16 may ie connected with the shunt; in the lllulllhd which will now he deserihed as may he other tools or elements that are neees zn'ily reroluhle in operation. The socket i is formed with uh enlargement or boss 20 eelumlly "lorn'ied with an outstanding rounded enlargement- 97. From the boss there extends :1 cross seetiondlly rounded stem 28 that is received in the socket The stem, e; its juncture with the boss is Formed with :1 rib 29 that is receirml in the slot 23, wherein, the stem is locked on the shunlr L2. The chimp or clutch nreniher is llll'tllll'fll on the stem as pro vi on the depressions in the ernls thereof will e.u gage the enlargement Z? on the extension 26 of the soehet member 9T3 thereln etleetivel holding the said socket on the tool.
